Answer by sponka for [3.1.0.11] No more WIFI connection [Jolla 1]

I have same problem -- my daily driver is Jolla C but for some time I have problem with responsivnes and decided to go back to Jolla 1. Since it was on Hossa, had to update it first to 3.1.0.11. Now it won't connect to home wifi :( If it helps, here's dmesg output on pastebin: https://pastebin.com/NTHfiszG EDIT: I tryed downgrade which didn't finish at all -- I had no idea that after Sailfish 3 this is not possible ... anymore -- learned hard way. Made factory reset, gone two times (2x!) through whole process (upgrade to 3.1.0.11 via GUI and via terminal). Last working version is 3.0.0.8., after that with direct upgrade to 3.1.0.11, wifi stops working. Not all networks are affected. I have problem at home (TL-WR1043ND v4 with dd-wrt), but no issue at work (some Mikrotik stuff).
